anyone have any idea on these 2 sounds...

[silvergsx623]

1st sound... when accelerating or braking between 10 and 25 mph there is a rappid pinging sound comming from around the transmission area.
it sounds like a small bell dinging. the faster the vehicle speed the faster the pinging.


2nd sound when crusing over 20 mph, there is a knocking/banging/thud sound sounds like its comming from the front drivers wheel area.
also its revelant to the vehicle speed... the faster the car goes the quicker the knocking.

only thing i can think of is maybe wheel bearing?:1zhelp:

have you ever had rodknock? or heard it?

 

[mkiiSupraMan18]

trans sound.... I have no idea...

Front end noise could be quite a few things:
Loose wheel, warped rotor, loose caliper/rotor, or any number of other loose things.

More detailed sounds owuld help.. is it a low sounding "ping" like a hammer or something hitting the bottom of the car or is it higher, like hitting two hammers together?

U talking about the Supra or the GSX?

 

[silvergsx623]

yeah my jdm motor was knocking.

this knock sound is very very simular... except for this sound is deeper than when it was rod knocking. more of a thud sound... RK was more of a matalic sound compaired to this
i know its not rod knock though, cause i can be rolling about 30 mph, mash in the clutch and the rpms drop... and the knocking sound keeps going and slows down as the cars speed slows down.

first thing i though was the wheel may be loose... the car kinda wabbles, it may just be very out of alinement. ( i bought it a few months ago and am in the process of restoring it) but all the lug nuts on the wheels are tight

the 2nd noise at the transmission....
sounds like... a childs bell on their bicycle, (that pitch of a sound) its a precessuive sound... not a gear or grinding sound.
or another example... similar to... when riding a rollar coaster, when you are being pulled up to the top of the hill... the click of the chain. that type of sound... but more like a bell sound.
if it comes down do it... i can make a video... lmao
i have no idea what it is

This is on the supra

you need to get under there and check the whole brake assembly if something is making that kind of noise its probably loose obviously not trying to talk down or something also i would check the ball joints and tie rods to see if they are in tact obviously again the tie rods probably in tact but the ball joints might be GONE. Just a suggestion its all i can think that would make the car shake.

 

[silvergsx623]

ok thanks, i understand. im just trying to get ideas of what all to check.

Thanks guys

anything else it could possably be?

 

[mkiiSupraMan18]

Was this motor/trans just recntly installed?

If so, you may have an additional spacer on the flywheel, TOB (or something) could be hitting the bolts if this is the case. I did it once, and it kinda sounds like that. Just another thought.

 

[PorterzSupra]

Yes rod knock and engine knock sounds are similar, in fact the computer will read rod knock as engine knock and retard the timing

 

[mkiiSupraMan18]

Oh, and I was just thinking about my last post, it's the clutch disk hitting the bolts in that scenario. Silly me. :icon_conf

 

[silvergsx623]

yeah i just swapped the motor and trans out 2 weeks ago.

hum... interesting, i put the spacer on the flywheel. i only had one because i reused my old flywheel. thanks mkiisupraman

rod knock? what do u mean by this and engine knock?
one of my rod bearings (in my engine) bit the dust and started knocking...

 

[silvergsx623]

hummm...

it still makes the sound if i have the clutch pedal all the way in.(when stopping/slowing down) does that tell u anything?

 

[mkiiSupraMan18]

Uhhh... been a while since I screwed with one, but 5 speeds don't have a spacer between the bolts and flywheel, do they? Someone will chime in I'm sure...

But I think that if the spacer was the problem, it would do it all the time. It's been 2-3 years since I did that. It's a mistake I like to try and forget. I freakin hate swapping trans... :icon_mad:

Ohh... check drive shaft bolts too... They make an awful racket when you drive w/ them loose. And don't take anyone's word on them being tight, get down and do it yourself. lol I dunno, thats deffinitely a thud sound, not a "bell", but could be like a roller coaster type sound though. Just trying to think of stuff for you to check. You DID read the warning or w/e in my sig, correct? :icon_bigg

 

[silvergsx623]

there is a ring that all 6 flywheel bolts go through that hold the fly wheel on... i figured that was a spacer of some sort...
yeah i don't like doin trans work either... lol

i'll double check the driveshaft bolts... imi 99% sure i got them tightened back down. but i will check agian

yeah thanks, all the ideas the better...
lmao yes i read your sig.... hense why im scared your the only one helping.... hahaha im just kiddin, thanks for the help so far

thanks for the ideas guys... this weekend i'll have time to get under there and check to see what i can find

 

[boost fiend]

how about pressure plate bolts? as far as wheel bearings in the front, i think you might call that more of a popping sound. check the driveshaft bolts. engine to trans bolts. double check all of it. im sure youll find it and hate yourself for a day or two over it.

 

[mkiiSupraMan18]

lmao yes i read your sig.... hense why im scared your the only one helping.... hahaha im just kiddin, thanks for the help so far

No prob, those who know what they are doing/talking about should be back monday-Friday 9-5. :icon_bigg

I'm still leaning toward something driveshaft related, the more I think about it.

 

[silvergsx623]

holy crap my front wheel was loose. dono how that happened suppose i just didn't torque the lug nuts down.
well that sloves one of the 2 sounds..

now just to find what the little dingind , bell like sound is...

im posative the pressure plate bolts are torqued down properly, i remember doublechecking them.
i checked all the bolts/nuts on the drive shaft today and they all were tight

 

[bensn8]

Check your flywheel bolts as well. Did you do some trans work on it? Did you replace the pilot bearing? Just some food for thought.

 

[silvergsx623]

ok.

i pulled the trans off the jdm motor that was in the car, but it on the rebuilt us block. i didn't replace anything in the trans.

it has a new center force clutch in it... has about 500 miles on it.

question: if it was flywheel bolts... wouldn't it make a sound at idle?
i can rev the motor up to 5 grand and it sounds perfect no sounds, only makes noise when the trans is spinning.
if im driving down the road with trans in gear it makes the noise, is i mash in the clutch it continues. once i get over about 30 ish mph the noise goes away. but as soon as i start slowing down the noise returns...

thanks for the help so far guys

[silvergsx623]

AH!

finaly, my buddy andy and i found my other noise yesterday.

you know the little black shield that goes around the drive shaft where the shaft goes into the transmission.
the driveshaft is scraping the cover... making a ding sound.. kinda sounds like an old phone/bell

he thumped the cover and it was the exact sound.

we believe it is doing this because the carrier bearing on the driveshaft seems to be very warn, in need of replacement. this is allowing extra play in the driveshaft... and is makin it strike the dust cover.

Thanks for all the help guys
